The correct answer is 8 because the given question is asking for the ASCII code of the lowercase Greek letter "epsilon." The ASCII code for the lowercase Greek letter "epsilon" is 101 in decimal. However, the question specifies that the ASCII code should be within the range of 0 to 1, so we need to find the remainder when dividing 101 by 2. The remainder is 1. Therefore, the ASCII code of the lowercase Greek letter "epsilon" within the given range is 1.
